Scott Morrison has declared the “lungs of the world” are burning as escalating fires ravage the Amazon rainforest.

“It’s very distressing,” the prime minister told Sky News in an interview aired on Wednesday.

“It’s often been described as the lungs of the world and they are on fire.”

The fires have drawn international concern because of the Amazon’s importance to the environment.

Leaders of the world’s seven largest economies have offered Brazil $30 million to help fight the Amazon fires.


But Brazil is poised to reject the “colonialist and imperialist” offer from the G7 nations.

British PM Boris Johnson meets Australian PM Scott Morrison for their bilateral talks during the G7 Summit in France last week.

Despite having the expertise and equipment to fight large fires, Mr Morrison again indicated Australia is likely to leave the massive firefighting battle to others, as it focuses on the upcoming bushfire season at home.

“We’ll carefully consider what requests are made – we’re concerned like everybody else is and we’d look to see what sort of arrangements are put in place,” Mr Morrison said.

“But we also have a lot of our own challenges to deal with within Australia.”

Labor’s foreign affairs spokeswoman Penny Wong earlier said the government should be proactive in offering practical help, arguing Mr Morrison shouldn’t “sit on his hands until he’s asked”.
